Abstract

Le protocole Nutrition as Medication (NAM) est un moyen innovant d’administrer les suppléments nutritionnels oraux (SNO), afin de prévenir la perte de poids et la malnutrition dans les établissements de soins de longue durée (ESLD). Une boîte à outils a été développée pour soutenir son implantation et son utilisation. Cette étude vise à évaluer l’implantation du protocole NAM, en utilisant la boîte à outils. Trois ESLD ont été recrutés via un échantillonnage de convenance. De plus, des employés, proches-aidants et résidents des ESLD ont été recrutés pour les entrevues qualitatives individuelles. L’adhésion au traitement, les raisons de non-consommation des SNO et les données sur l’adéquation aux prescriptions NAM ont été extraites à partir des dossiers médicaux. Un test de Kruskal-Wallis a été effectué pour détecter toute différence entre les taux d’adhésion des différents ESLD. Des entrevues semi-dirigées ont été menées avec les participants afin d’identifier les barrières et les facilitateurs à l’implantation. Une analyse thématique a été réalisée pour identifier les thèmes. Le degré d’adhésion global aux SNO était de 90,8 % et aucune différence significative entre les ESLD n’a été détectée. La principale raison de non-consommation des SNO était le refus; cependant, plusieurs raisons de non-consommation n’étaient pas inscrites dans les feuilles d’administration des médicaments. Le rapport entre le nombre de prescriptions attendues et le nombre de prescriptions réelles variait entre 1,7 et 3,3, indiquant que le protocole NAM était sous-utilisé. Les personnes interviewées ont décrit quatre thèmes principaux : 1) la planification de l’implantation; 2) l’éducation et la diffusion de l’information; 3) les facteurs logistiques; et 4) la perception envers le protocole NAM. À travers ces thèmes, une communication efficace s’est révélée être d’une grande importance. Malgré certaines barrières, les participants ont exprimé leur appréciation envers le protocole NAM, notammen, The Nutrition as Medication (NAM) program is an innovative way to administer oral nutritional supplements (ONS) to counteract weight loss and malnutrition in long-term care (LTC) settings. A toolbox has been developed to sustain its implementation and use. This study aims to evaluate the implementation of the NAM program using this toolbox. To this end, three LTC settings were recruited using convenience sampling. LTC employees, caregivers and residents were recruited for qualitative interviews. Adherence to treatment, reasons for non-consumption of ONS and data on the adequacy of NAM prescriptions were extracted from patient charts. Kruskal-Wallis tests were performed to detect differences in adherence rates among LTC settings. Semi-structured interviews were conducted with participants to identify barriers and facilitators to the implementation of the NAM program. A thematic analysis was conducted to identify emerging themes. Overall adherence to treatment was 90.8 %, with no significant difference between settings. The main reason for non-consumption of ONS was refusal; however, in many cases, reasons for non-consumption were not mentioned in the Medication Administration Record. The ratio between expected and actual ONS prescriptions ranged from 1.7 to 3.3, suggesting that the NAM program as undersused. Interviewees described four main themes: 1) Implementation planning; 2) Education and dissemination of relevant information ;3) Logistic factors; and 4) Perceptions towards the NAM program. Through these themes, the importance of effective communication was highlighted. However, despite the communication barriers, participants expressed their appreciation towards the NAM program, notably because of the perceived benefits for the residents’ health and quality of life. To conclude, treatment adherence was high in all settings. LTC employees appreciated the NAM program and expressed their desire to maintain its use. However, elements related to communicati

Abstract

Higher dietary protein, alone or in combination with physical activity (PA), may slow the loss of age-related muscle strength in older adults. We investigated the longitudinal relationship between protein intake and grip strength, and the interaction between protein intake and PA, using four longitudinal ageing cohorts. Individual participant data from 5584 older adults (52 % women; median: 75 years, IQR: 71·6, 79·0) followed for up to 8·5 years (mean: 4·9 years, SD: 2·3) from the Health ABC, NuAge, LASA and Newcastle 85+ cohorts were pooled. Baseline protein intake was assessed with food frequency questionnaires and 24-h recalls and categorized into < 0·8, 0·8–<1·0, 1·0–<1·2 and ≥ 1·2 g/kg adjusted body weight (aBW)/d. The prospective association between protein intake, its interaction with PA, and grip strength (sex- and cohort-specific) was determined using joint models (hierarchical linear mixed effects and a link function for Cox proportional hazards models). Grip strength declined on average by 0·018 SD (95 % CI: –0·026, –0·006) every year. No associations were found between protein intake, measured at baseline, and grip strength, measured prospectively, or rate of decline of grip strength in models adjusted for sociodemographic, anthropometric, lifestyle and health variables (e.g., protein intake ≥ 1·2 v· < 0·8 g/kg aBW/d: β = –0·003, 95 % CI: –0·014, 0·005 SD per year). There also was no evidence of an interaction between protein intake and PA. We failed to find evidence in this study to support the hypothesis that higher protein intake, alone or in combination with higher PA, slowed the rate of grip strength decline in older adults.

Abstract

© The Author(s) 2021. Published by Oxford University Press on behalf of the American Society for Nutrition. BACKGROUND: Dietary protein may slow the decline in muscle mass and function with aging, making it a sensible candidate to prevent or modulate disability progression. At present, studies providing reliable estimates of the association between protein intake and physical function, and its interaction with physical activity (PA), in community-dwelling older adults are lacking. OBJECTIVES: We investigated the longitudinal relation between protein intake and physical function, and the interaction with PA. METHODS: We undertook a pooled analysis of individual participant data from cohorts in the PROMISS (PRevention Of Malnutrition In Senior Subjects in the European Union) consortium (the Health Aging and Body Composition Study, Quebec Longitudinal Study on Nutrition and Successful Aging, Longitudinal Aging Study Amsterdam, and Newcastle 85+) in which 5725 community-dwelling older adults were followed up to 8.5 y. The relation between protein intake and walking speed was determined using joint models (linear mixed-effects and Cox proportional hazards models) and the relation with mobility limitation was investigated using multistate models. RESULTS: Higher protein intake was modestly protective of decline in walking speed in a dose-dependent manner [e.g., protein intake ≥1.2 compared with 0.8 g/kg adjusted body weight (aBW)/d: β = 0.024, 95% CI: 0.009, 0.032 SD/y], with no clear indication of interaction with PA. Participants with protein intake ≥0.8 g/kg aBW/d had also a lower likelihood of incident mobility limitation, which was observed for each level of PA. This association seemed to be dose-dependent for difficulty walking but not for difficulty climbing stairs. No associations between protein intake and other mobility limitations transitions were observed. CONCLUSIONS: Higher daily protein intake can reduce physical function decline not only in older adults with protein intake below the current RDA of 0.8 g/kg BW/d, but also in those with a protein intake that is already considered sufficient. This dose-dependent association was observed for each level of PA, suggesting no clear synergistic association between protein intake and PA in relation to physical function. publishersversion published

Abstract

Background: Consumption of a prudent dietary pattern rich in healthy nutrients is associated with enhanced cognitive performance in older adulthood, while a Western dietary pattern low in healthy nutrients is associated with poor age-related cognitive function. Sex differences exist in dietary intake among older adults; however, there is a paucity of research examining the relationship between sex-specific dietary patterns and cognitive function in later life.Methods: The current study aimed to investigate sex differences in the relationship between sex-specific dietary pattern adherence and global cognitive function at baseline and over a 3-year follow-up in 1268 community-dwelling older adults (Mage = 74 years, n = 664 women, n = 612 men) from the Quebec Longitudinal Study on Nutrition and Successful Aging (NuAge). A 78-item Food Frequency Questionnaire was used to estimate dietary intake over the previous year. Sex-specific dietary pattern scores were derived using principal component analysis. Global cognition was assessed using the Modified Mini-Mental State Examination (3MS).Results: Adjusted linear mixed effects models indicated that a healthy, prudent dietary pattern was not associated with baseline cognitive performance in men or women. No relationship was found between Western dietary pattern adherence and baseline cognitive function in women. Among men, adherence to an unhealthy, Western dietary pattern was associated with poorer baseline cognitive function (β = - 0.652, p = 0.02, 95% CI [- 1.22, - 0.65]). No association was found between prudent or Western dietary patterns and cognitive change over time in men or women.Conclusions: These findings highlight the importance of conducting sex-based analyses in aging research and suggest that the relationship between dietary pattern adherence and cognitive function in late life may be sex-dependent.
